However, there are many stable compounds that can be viewed as derivatives of tetraaminoethylene, with various organic functional groups substituted for some or all hydrogen atoms. These compounds, which have the general formula (R2N)2C=C(NR2)2, are collectively called tetraaminoethylenes.
General chemical structure of tetraaminoethylene derivatives
Tetraaminoethylenes are important in organic chemistry as dimers of diaminocarbenes, a type of stable carbene with the general formula (R2N)2C:.
Reactions
- Tetraaminoethylenes react with acids to give formamidinium salts.
